Nat Fraser was jailed over wife Arlene's death
Nat Fraser has been told by appeal judges that his latest legal challenge against his conviction for murdering wife Arlene can go no further.
Fraser, 51, is serving a life sentence but continues to protest his innocence.
In 2003, Fraser was ordered to serve at least 25 years for the "evil" murder of 33-year-old Arlene, who vanished from Elgin, Moray, in April 1998.
Judges at the Court of Criminal Appeal in Edinburgh ruled his latest legal move was incompetent.
Judges had originally thrown out an initial appeal against his conviction.
Fraser then asked judges at the Court of Criminal Appeal if he could appeal to the Privy Council. They refused that bid.
Fraser's legal team claimed that when the Court of Criminal Appeal in Edinburgh dealt with his challenge to his conviction it did not consider properly issues thrown up by human rights legislation.
Fraser appeared in court on Friday alongside Luke Mitchell, 21, who was jailed for killing Jodi Jones.
Mitchell is serving a minimum of 20 years for stabbing his girlfriend to death.
The 14-year-old's body was found in June 2003 in woods beside a path which joined her house in the Easthouses area of Dalkeith with the Mitchell home in the Newbattle district.
Mitchell claims he did not get a fair chance to present new DNA evidence because of difficulties getting legal aid to carry out scientific inquiries.
He was allowed more time to seek legal advice, and a final ruling will come at a later date.
